The *Furen Liangfang* (Excellent Prescriptions for Women) states: After childbirth, even if there are no diseases, one should pay attention to recuperation and regulate the Spleen and Stomach, consuming nutritious food. In this way, the Zang-Fu organs will easily return to balance, Qi and Blood will naturally harmonize, and various diseases will not arise. Jiawei Sijunzi Tang (Modified Four Gentlemen Decoction) and Sishun Lizhong Wan (Four-Directional Regulating Middle Pill) are suitable for regular consumption within one hundred days postpartum.

The *Chanbao Xinshu* (New Book of Obstetrics) states: Postpartum Qi and Blood are suddenly deficient, so it is appropriate to tonify heavily. However, since lochia has not yet cleared, using tonics may cause blood stasis to stagnate. Only Shenghua Tang (Decoction for Generating the New) offers tonification within its blood-invigorating action; it can generate new blood and transform old stasis, making it a truly comprehensive remedy. Siwu Tang (Four Substances Decoction), on the other hand, has misled many in the postpartum period. Dihuang (Prepared Rehmannia Root) has a cloying nature, and Baishao (White Peony Root) is sour and cold, which damages the vitalizing Qi. Shenghua Tang removes these two herbs and adds warming and blood-invigorating agents. For instance, regarding pain caused by "Erzhen" (a mass of retained blood in the uterus), people commonly use formulas that dissipate masses and invigorate blood first, before considering tonification. Others mix blood-dispersing and tonifying methods, failing to realize that while old stasis should be resolved, new blood must also be nourished. If one focuses solely on attacking the old stasis, the new blood will be damaged. People use Huisheng Dan (Revival Pill) to treat postpartum conditions, aiming to break blood masses, expel the placenta, and abort dead fetuses. Although quick effects are seen, the Yuanqi (Original Qi) inevitably suffers depletion. Shenghua Tang is named after the properties and functions of its ingredients. Postpartum blood masses should be eliminated, and new blood should be generated. If only dispersing methods are used, new blood cannot be formed; if only generating methods are used, old stasis will stagnate. Examining the properties of these herbs, the formula mainly consists of three ingredients: Chuanxiong (Szechwan Lovage Rhizome), Danggui (Chinese Angelica Root), and Taoren (Peach Kernel). These are good at attacking old stasis and rapidly generating new blood. They are assisted by Heijiang (Charred Ginger Rhizome) and Zhigancao (Honey-fried Licorice Root), which guide the three main herbs into the Lung and Liver meridians to generate blood and promote Qi flow. The five ingredients together form a prescription where invigorating blood contains tonification, making it truly the sacred medicine for postpartum care.
Once the fetal membranes rupture, decoct one dose immediately and administer it as soon as the baby's head emerges, regardless of whether it is a premature or full-term birth. Even if the delivery was smooth and the woman is young and healthy, she should still take one or two doses to eliminate blood masses and generate new blood, thereby avoiding the risk of Xueyun (blood dizziness/fainting). If the woman had weak constitution during pregnancy and presents with critical symptoms postpartum, frequent administration is acceptable until the illness recedes. If one were to take only one dose as usual, how could it support the nearly exhausted Qi and Blood? If there is pain from blood masses, add 3 fen of Rougui (Cinnamon Bark), 3 fen of Honghua (Safflower Flower), and 5 qian of Yimucao (Motherwort Herb). If severe exertion leads to metrorrhagia (profuse uterine bleeding) with physical collapse and pallor, add 3–4 qian of Renshen (Ginseng Root and Rhizome). If sweating and shortness of breath occur, double the dosage of Renshen.

Shenzhai’s commentary: The Shenghua Tang formula is recorded in the *Chanbao Xinshu*. For all postpartum conditions, this formula can be modified accordingly; it is quite stable and worthy of emulation, hence it is recorded here. It complements the *Furen Liangfang*, which recommends Jiawei Sijunzi Tang and Sishun Lizhong Wan. One treats postpartum syndromes, while the other regulates the Spleen and Stomach; they can be consulted together.
